Also known as jam nuts, these are about half the height of standard hex nuts. Use them in low-clearance applications or jam one against another nut to hold it in place. About half the strength of medium-strength steel thin nuts, use them for light duty fastening applications, such as securing access panels. Some of these screws meet ISO and DIN dimensional standards.

Nuts with fine and extra-fine thread spacing are less likely to loosen from vibration than nuts with coarse thread spacing.

About half the height and 10% wider than standard nylon-insert locknuts, use these in low-clearance applications or jam one against an extra-wide hex nut to hold it in place. The nylon insert grips the bolt to resist loosening without damaging threads. They're reusable, but their holding power lessens with each use. Comparable in strength to Grade 8 bolts, these locknuts are about three times stronger than low-strength steel extra-wide thin locknuts.

Black-phosphate steel locknuts resist corrosion in wet environments.

Use these nuts with precision AN sleeves and fittings to provide a tight metal-to-metal seal on stainless steel tubing that is flared to 37°. The threads are Class 3B and adhere to tighter tolerances than other nuts. They are made to exact AS (formerly AN) specifications.

304 stainless steel nuts have very good corrosion resistance.
